901491 ÷ 46 
The aim is to understand the frequency of 46 in 901491.

Moving on to step 1:
If we divide 9 by 46, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 46

Advancing to step 2:
46 goes into 90 1 times with a remainder of 44.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 46 from 90 and we're left with 44.
Append the next digit (1) from the dividend to 44 and continue with: 441 / 46

Moving on to step 3:
If we divide 441 by 46, we get 9 and a remainder of 27.
The next digit of our result is 9. 
Result so far: 19.0
The remainder is 27 after subtracting 414 from 441.
Grab the next digit (4) from the dividend, add it to 27, then carry on: 274 / 46

Step 4:
46 can be fit into 274 5 times, resulting in a remainder of 44.
Record the quotient 5 as the next digit in the result. 
Result so far: 195.0
Subtracting 230 from 274 leaves us with 44.
Append the next digit (9) from the dividend to 44 and continue with: 449 / 46

Going ahead to step 5:
449 divided by 46 is 9 with a remainder of 35.
Write down 9 as next digit of the result. 
Result so far: 1959.0
Deduct 414 from 449 and we're left with 35.
Append the next digit (1) from the dividend to 35 and continue with: 351 / 46

On to step 6:
46 goes into 351 7 times with a remainder of 29.
Put 7 as the next digit of the answer. 
Result so far: 19597.0
If we subtract 322 from 351, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 7:
When dividing 290 by 46, we get 6 with a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 19597.6
Subtract 276 from 290 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 8:
46 can be fit into 140 3 times, resulting in a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 19597.63
Deduct 138 from 140 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 9:
The number 46 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 19597.63
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
46 can be fit into 200 4 times, resulting in a remainder of 16.
The next digit of our result is 4. 
Result so far: 19597.6304
If we subtract 184 from 200, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 11:
46 can be fit into 160 3 times, resulting in a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 19597.63043
Subtracting 138 from 160 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 12:
220 divided by 46 is 4 with a remainder of 36.
The next digit of our result is 4. 
Result so far: 19597.630434
The remainder is 36 after subtracting 184 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 13:
360 divided by 46 is 7 with a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 19597.6304347
Subtract 322 from 360 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 14:
When dividing 380 by 46, we get 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 19597.63043478
Subtracting 368 from 380 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 19597.63043478 with a remaining 1.2e-08.
